Patented July 18, 1933 PATENT OFFICE MICHAEL J. nurrmor BROOKLYN, NEW YORK SAFETY RAZOR AND HAIR CUTTER Application filed June 3, 1931. Serial No. 541,809.

This invention relates to safety razors and more particularly to devices of this type which are also adapted for hair cutting. This invention is a continuation in part of my copending application Serial Number 482,577, filed September 17, 1930.

The objects of this invention, among others, are: First, to provide a simple, compact assembly of units which may be easily and quickly assembled for cutting the hair of the head; to provide such an assembly which may be easily and quickly assembled to out the hair of the head in different lengths; to provide such a device in which the operation of hair-cutting is entirely comfortable to the one whose hair is cut; to provide such an assembly of units as may be quickly and easily disassembled and quickly and easily assembled as a safety razor for cutting the hair of the face or shaving; to provide light, simple, durable and cheaply manufactured parts throughout; to provide simple and certain operating mechanism; and to provide a device adapted for use with the standard Gillette safety razor blade now on the market. Other objects may appear as the description proceeds.

Reference is now made to the drawing which is hereby made a part of this specification in which Figure 1 is an exploded perspective View.

Figure 2 is a plan view of the hair-cutting assembly,

Figure 3 is an end view of the hair-cutting assembly with the parts of the assembly shown in section, and

Figure 4 is a plan view of a Gillette safety razor with the usual post handle removed and my horizontal handle in place thereof.

Similar numerals of reference refer to like parts throughout the drawing, in which the conveXly curved base or contact piece 1 is similar to that of the ordinary Gillette safety razor except that it has two end posts 2 of greater length than the similar posts and a central, threaded assembly post 3 also greater in length. than the corresponding post. Placed to overlie the base 1 is one of several transversely curved spacing portions 1 of the same outline as the base 1, the upper and 3. Usually a set may have three spacing portions 1 of varying thickness adapted to vary the distance of the superimposed razor blade 1 6 from the contact surface of the base 1 for hair-cuts of different length. The Gillette blade has the cutaway central portion 7 for all support on the posts 2 and 3 and the two cutting edges' 8. Overlying the razor 6 is the combined guard and comb 9, having holes 10 for posts 2 and 3. The body 11 may be curved as desired preferably like the usual guard of a Gillette safety razor. Proj ecting from both sides of the body 11 are inwardly curved tines or teeth 12 spaced apart and of any desired size and spacing. On the four outside teeth or tines 12 on the outer surfaces at points slightly removed from the ends of the teeth or tines there are spacing studs let with rounded heads. The protuberance of said spacing studs from the teeth is substantially the same as the combined thickness of the contact piece and the spacing portion. These serve to prevent unpleasant pressure of the ends of the tines 12 on the scalp and also guide the operator in varying the length of the haircut. The handle 15 has an extension 16 of any desired design and size and a flat portion in which are holes 17 adapted to receive the posts 2. Another hole underlies the serrated cylindrical cap 18 which has a screwthreaded hole 19 shownin Figure 3 and adapted to engage with the screwthreaded post 3 and in this manner draw the base 1 toward the handle 15 thereby securely locking all of the parts of the assembly in the assembled position. The cap 18 is provided with an outwardly extending flange 18a which is rotatably held on the handle 15 by means of the annular collar 20 which has an inwardly projecting flange 21 which overlies the flange 18a. The collar 20 is secured to a washer 22 which is in turn fixed on the upper surface of the handle 15.

It is now obvious from the foregoing description that by a few reverse turns with the thumb and finger of the cylindrical serrated cap 18 the handle 15 is quickly disengaged from the post 3 and the assembly can be broken for the quick and facile insertion of a thicker or of a thinner spacing portion 4 or in the case of the use of one of my modified forms for the insertion of another slotted spacing portion. If the assembly contains also a guard ofthe usual Gillette safety razor the base 1, the razor blade 6, the guard and the handle 15 may be quickly and easily assembled to the form of the usual Gillette safety razor but with a lateral handle. Or if preferred the usual post handle may be used.

I have shown and described a preferred embodiment of my invention, but many changes in details.'willyreadily occur to those skilled in the art,'so therefore I do not choose to limit myself except as in the appended claim.

Iclaim:

A combined safety razor and hair cutting ing studs from said teeth being substantially the same as the combined thickness of the contact piece and the spacing portion, and a handle adapted to lock With the post and secure a razor blade against the guard "on the outer surface thereof and the other elements in the assembled position for hail-cutting as above enumerated.
